TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Jan. 11, 1910.

Application filed October 16, 1907. Serial No. 397,744.

To all whom 'it may concern:

Be it known that 1, (IMO E. Yaw, a citizen of the United States, andresident of Arlington, in the county of Hudson and State of New Jersey,have invented certain newand useful Improvements in Type-VritingMachines, of which the following is a specification.

My invention relates to the paper feeding mechanism of typewritingmachines and has for its object to provide improved devices of the classspecified.

To the above and other ends the invention consists in the features ofconstruction, combinations of devices and arrangements of parts,hereinafter described and particularly pointed out in the claims.

One form of the invention is illustrated in the accompanying drawings,wherein- Figure l is a fragmentary top plan view of a platen and platenframe showing my invention in combination therewith. Fig. 2 is asectional view taken transversely of the platen and showing the platen,parts of the platen frame and my improved paper feeding devices, saidview being drawn to a larger scale than Fig. 1. Fig. 3 is a bottom planview of my improved devices. Fig. a is a longitudinal sectional view ofmy improved devices. Fig. 5 is a view corresponding to Fig. a butshowing some of the parts in different relations from those in whichthey appear in said Fig. 1. Fig. 6 is a fragmentary front elevation ofthe platen and platen frame and showing my invention, the parts thereofbeing in the same relations as those in which they appear in Fig. 5.

The drawlngs show the invention applied to a visible writing machine,but said invention may be adapted to other styles of machines.

A platen 1 is mounted on an axle 2 which bears at its ends in the sideor end plates or bars 3 of a platen frame, the latter also comprisingcross bars 4 and 5 connecting the end bars. The platen is provided withsuitable line spacing mechanism and at its rear and under sides is ormay be provided with paper controlling devices including a paper table6, a paper apron 7 supporting a scale 7 and feed rollers 8 and 9 (Fig.2).

Extensions or arms 10 project forwardly of the platen from the end bars3 and are bent upwardly at their front end portions as indicated at 10,the tops of the parts 10 being connected by a cross bar 11 which isrectangular in cross section and may be suitably secured to the parts 10as by screws 12. The bar 11 is some distance in front of the platen andabout on a level with the top thereof.

My improvements in paper controlling devices comprise what is usuallycalled a paper finger, together with its supporting means. One or moreof said paper fingers may be arranged on the rod or bar 11. The supportfor each paper finger is slidable lengthwise of the bar and comprises aU-shaped. part 13 formed preferably of sheet metal and arranged toembrace the bar 11 closely at the top, bottom and front sides thereof.The top and bottom portions of the part 13 project rearwardly beyond therear face of the bar 11 and receive between them the forward portion 14-of a supporting member 15, as shown clearly in Figs. 4 and 5. Theportion 14 is cut down from the body of the supporting member 15 to fitbetween the sides of the member or part 13 and may be secured in a fixedrelation with said member 13 by rivets 16. The forward end of theportion 1a abuts against the rear face of the bar 11, the constructionbeing such that when the members 13 are 15 are assembled, they togetherembrace the bar 11 closely on its four sides and may be moved onlylengthwise of said bar, being maintained by friction. in adjustedposition. A finger piece or handle 17 is provided with a shank 18connecting the members 13 and 15, The finger piece 17 extends verticallyupward from the member 13 and affords a convenient means formanipulating the paper controlling finger and its supporting means in adirection lengthwise of the platen. The member 15 extends horizontallyrearward toward the platen and is in the nature of a socket being formedwith a cylindrical opening or bore 19 which receives a cylindricalslidable member or plunger 20. The latter enters the bore at its openrear end and has a sliding fit therein. The plunger carries a paperfinger proper, as will presently be described,

and is adapted to slide back and forth in the bore of the socket-likemember 15, being normally prevented from rotary or. turning movement bya projection or shouldered screw 21, which is secured in the undersideof the plunger 20 and the head of which projects radially outwardthrough and beyond a slot 22 cut in the under side of the member 15. Asshown clearly in Fig. 8, the di ameter of the head of the screw 2 bearssuch a relation to the width of the slot 22 that while the plunger 20may be reciprocated back and forth in a right line it is prevented fromturning or rotating by the contact of the screw 21 with the sides of theslot 22. Said plunger may, however, be moved bodily forward to theforward end of the slot 22 where the slot is provided with an angular orlateral extension 23 of sufficient width to receive the screw 21 and toafford a limited turning or rotary movement of the plunger 20 when ithas been moved to this forward position. The slide or plunger 20 isconstantly urged or pressed rearward toward the platen by a coiledspring 2t which is arranged within the bore 19 and abuts at its rear endagainst the plunger 20. The forward end of the spring bears against ashort cylindrical abutment 25 slidable within the bore 19 and which isformed with a stem extending rearwardly some distance through the springand serving as a guide therefor. vThis member or abutment 25 receives aprojection or screw 27, the shank of which extends radially outwardthrough a slot 28 cut through the underside of the members 18 and 15 andextending lengthwise of the member 15 as shown in Fig. 3. The head ofthe screw 27 is out side of the slot 28 and is rounded to provide aconvenient means of manipulating the slidable abutment or plunger 25.The abutment 25 may be adjusted in two positions, illustrated in Figs. 5and 4-. In Fig. 5 the spring 24 is shown as pressing the abutmentforward as far as it can go, the limit of forward movement beingdetermined by the shank of the screw 27 abutting against the forward endof the slot 28. As has been said the head of the screw 27 serves as afinger piece and by means of this the abutment 25 may be forcedrearwardly compressing the spring 24 until the shank of the screw 27reaches the rear end of the slot 28 where said slot is formed with anangular or lateral extension 28 (Fig. 3). The extension or notch enablesthe abutment 25 to be rotated until the shank of the screw 27 enterssaid extension, after which the handle may be released, the spring 24thereupon forcing the screw 27 forward and looking it and the abutmentagainst the forward curved face of the extension 28. This constructionenables the tension or force of the spring 241- to be varied, therebypermitting the cooperation of the paper finger with the platen to bevaried as will hereinafter be explained more fully.

The rear end portion or head 20 of the plunger 20 is at an angle to theplunger proper, being inclined downwardly toward the platen. The head isembraced on two of its flattened sic es by the cars 29 of the paperfinger. The .latter also comprises a guiding portion or finger proper30, the ears being bent at right angles therefrom and the part 30extending downwardly over the front face of the platen, the finger beingcurved to conform thereto. The ears 29 are perforated to receive a pin31 which passes through the upper end portion of the part 20 of theplunger and at its ends has knurled heads 31 by which the plunger andthe paper finger may be manipulated conven iently. Thehead 20 slotted asindicated at 32 and. arranged in the slot is a guide and feed rollerpivoted at 3% and projecting through a cut-out at the upper end of thelinger 30. the construction being such that the roller 3 may contactwith the platen or the paper thereon. The pivot 3 1 may be a rivet whichalso passes through the ears 29 of the paper linger and is headedoutside said ears. The paper finger is maintained in fixed relation withthe head 2d by the rivet and, pin 31 so that the paper finger bears afixed relation to the plunger 20.

The spring 2-1-, of course, presses the finger proper 30 and the roller33 against the platen and enables them to guide and C011 trol. the paperand cause it to pass upwardly and outwardly from the machine smoothlyand evenly. The srrew 21 engaging with the sides of the slot maintainsthe axis of the roller 33 parallel with the platen axle, thus prerentingthe paper or work sheet from being guided crookedly. For ordinary paperthe abutment will be maintained in the position shown in Fig. 5, butwhen it is desired to write on a card or stiff paper, pressure on thefinger 30 and roller 33 against the platen may be increased byincreasing the pressure of the spring 24, this being done by adjustingthe abutment 25 to its rear position as shown in Fig. l.

When it is desired to render the paper finger inoperative the knurledheads 31 may be grasped and the paper finger and slidable member orplunger 20 pressed toward the front of the machine until the screw 21reaches the forward end of the slot 22, after which the paper finger andplunger may be turned about the axis of the plunger until the screw 21looks in the extension or notch 28 of the slot 22, thereby maintainingthe parts in inoperative position, which position is indicated in Figs.5 and 6. In adjusting the paper finger and its support lengthwise of theplaten it is preferable to first lock the paper finger in inoperativeposition as shown in the last mentioned figure so that the devices maybe moved freely along the bar 11 without generating any friction betweenthe platen and the paper finger.

It will be noted that the paper finger is mounted on a slidable member,which slidable member and its support are movable in directions at rightangles to each other; and that the support or plunger carrying the paperfinger is movable at right anglesto the platen and platen axle.

Various changes may be made without departing from my invention. Forexample, the slots 22 and 28 shown as formed in the under side of themember 15 may be formed or provided at other sides of said member, asfor instance on the top thereof, and the screws or members 21 and 27 mayproject from their associate parts upward through the slots instead ofdownward as shown.
